BARATARIA BAY, LA - DECEMBER 05: Marsh grasses covered in oil from the BP oil spill are seen December 5, 2010 in Barataria Bay, Louisiana. Nearly eight months after the spill, oil remains along the shoreline of some of the barrier islands in the area and has killed off sections of marsh grass. Some of the islands are nesting areas for birds. BP lawyers said that government estimates of the size of the oil spill are too large in a dispute that will mark how many billions of dollars in fines the oil giant will have to pay.
